VLBI Imaging of the Gravitational Lenses B1422+231 and MG J0414+0534 (VLBI) observations at 8.4 GHz on 23rd November 1997. We present also a lens model for MG J0414+0534, which reproduces the core positions and flux densities of the VLBI images, combining a singular isothermal ellipsoid with external shear, and a singular isothermal sphere to represent, respectively

Daily Monitoring of the Gravitational Lens QSO 2237+0305 at the Nordic Optical Telescope the Nordic Optical Telescope. We report on some technical aspects of the observations and the quality of the data. We have developed a photometric model for obtaining the light-curves of the four QSO components.

The Origin of S0 Galaxies in Clustersare modeled as a thin exponential slab of cold gas, a stellar disk, bulge, and dark matter halo. The interaction of galaxy with the ICM is studied by means of a 3-dimensional non-symmetric high-resolution hydrodynamic code for gaseous matter, coupled with a N-body code for the collision-less matter.

The Galaxy Cluster Coreter potential) on the central cluster environment (shape and normalization of the luminosity function and density profile) and vice versa. We find no significant dependence between the luminosity function of the core cluster galaxies and the above BCG properties. Moreover, there is no apparent segre

The Coma Cluster of Galaxies: Spectral Classification and Star Formation with the Sloan Digital Sky pic system in June 1999: an observation of the Coma cluster of galaxies. Our data samples the Southern part of this cluster, out to the virial radius. We outline here the main characteristics of the SDSS spectroscopic systems and provide spectral classifications for 196 Coma galaxies. We have invest

Star-Forming Galaxies from the UCM-CIDA-YALE Surveyn and evolution of galaxies. The value for the SFR in the local universe is very dependent on the shape of the luminosity function and in particular on the a parameter. The UCM-CIDA-YALE survey (UCY) has grown to address this problem, among others. Using the objective-prism technique, we have been a
